When using my Verizon HTC Thunderbolt running CyanogenMod to call my wife's Verizon HTC Incredible, also running CyanogenMod, it always goes straight to Voice Mail. I can call other Verizon phones with no issue and my wife can call me with no issue and my wife can receive calls from other Verizon lines with no issue and she can call me with no issue. Issue is only from my phone to hers. I called Verizon and they said it is not a network issue and suggested an installed application might be causing the issue. They suggested to put both phones into Safe Mode boot. I was able to do this for Incredible, but failed using the directions they provided for the Thunderbolt. They said after boot starts, hold down volume down key for boot process on Thunderbolt.
How can I debug this issue of my phone going straight to Voice Mail? What would cause just my phone to experience this issue? Any advise and suggestions would be appreciated.
